This past weekend, B has been extremely clingy and fussy. I'm not sure if it's because he's trying to master crawling (he rocks on all 4s) and he's frustrated or he is in pain from his 2nd bottom teeth coming in. He just turned 8 months on 1/31, so maybe it's a wonder week? I'm just curious what is going on because he is normally so laid back and this weekend he was a fuss pot.
